The invention provides an aerial ladder chassis structure, and belongs to the technical field of aerial ladder chassis, the aerial ladder chassis structure comprises a frame, one end of the frame is movably connected with front support legs, a front first-stage support leg and a front second-stage support leg are arranged between the front support legs, the front first-stage support leg is movably connected with the front second-stage support leg, and the front second-stage support leg is movably connected with the front first-stage support leg. A rear base is arranged at the other end of the frame, two rear supporting legs are arranged in the rear base, the two rear supporting legs are in a splayed shape, a connecting plate is rotationally connected in the rear base, the other end of the connecting plate is fixedly connected with the rear supporting legs, the rear base is movably connected with the rear supporting legs through lifting oil cylinders, and the lifting oil cylinders are connected with the connecting plate. The two ends of the lifting oil cylinder are hinged to the rear base and the rear supporting leg respectively. The problem that when the scaling ladder rotating disc rotates, the rear supporting legs are prone to making contact with the ladder arms, and the scaling ladder operation range is affected can be solved.

    本发明提供了一种云梯车底架结构,属于云梯底架技术领域,该云梯车底架结构包括车架,所述车架一端活动连接有前支腿,所述前支腿之间设有前一级支腿和前二级支腿,所述前一级支腿和前二级支腿活动连接,所述车架的另一端设有后基座,所述后基座内设有两根后支腿,两根所述后支腿呈八字形,所述后基座内旋转连接有连接板,所述连接板另一端与所述后支腿固定连接,所述后基座与所述后支腿通过抬升油缸活动连接,所述抬升油缸两端分别与所述后基座和后支腿铰接;本发明能够解决云梯旋转盘转动时后支腿容易与梯臂接触,影响云梯作业范围的问题。
